Is leaf drop always a sign of death?

Not at all. It is often just the plant's way of reacting to stress. With proper care, it will usually grow new leaves.

Can pests cause leaf drop?

Yes, aphids suck the sap from the plant, which weakens the connection between the leaf and the stem. This often leads to the leaf falling off.
